Toallwhom it may concern: f

Be it known that I CHARLES L. STILns a citizen of the United States,residing at lumbus, in thecounty of Franklin and State of Ohio, haveinvented'a new and useful Improvement in Feed-Gages forPrinting-Presses, of which the following is a specification. T

The'present invention relates to an improved feed gage or gage pin, foruse in connection with platen printing presses, wherein the t mpan sheetis employed on the platen o the press and the gage pin isinserted orsecured in the sheet,,to facilitate the feeding of the sheets tobeprinted to the press and regulate and maintain the proper position ofthe sheets to be printed as they are presented to the type. i T Theprimary ob'ect of the invention is to improve the construction of thedevicesof this character in certain particulars of con struction, torender the device more durable and better braced when pinned or securedto the tympan sheet by theprong entered therein: to render more stablethe adjustable slide tongue so that it will remain in its fixed positionwithout likelihood of disarrangement and to so construct the gage headas to prevent the tongue being moved to such position as to endanger thetension feet, during the action of the platen, and to this end theinvention resides in certain novel combinations and arrangements ofparts as hereinafter more specifically described and claimed. T

In the accompanying drawings one complete example of the physicalembodiment of theinvention is illustrated, and in addition, amodifiedform of the invention is depicted, showing the best modes I have so fardevised for the practical application ofthe principles of the invention.Figure 1 is a planview showing a portlon of the platen of the'press withthe tympan sheet and the feed gage secured thereto, the corner of asheet to be printed also being shown. T

detached.

Fig. 3 is a'plan view of thegage.

ig. 4 is asectional view of the gageon line 1'1 of Fig.3.

. Fig. 5 is an enlarged view of a of the blank from which the gage head,shanks and tongue are folded.

Fig. 6 isv a front elevation of the gage head, with the tongue omitted.T

Fig. 7 is a rear elevation of the device. Fig. 8 illustratesamodified'form' of the shanks, and

Fig. 9 is an edge view of one of the tension fingers of the shanks inFig. 8.

p In the preferred form of the invention as illustrated in the drawingsI have shown sufiicient portions of the platen 1, the tympan sheet 2,and a sheet to beprinted as 3, to illustrate the applicationthereto ofthe gage which is secured by passing the sharpened end of the prong 4through the tyrna pan sheet as usual to, hold the gage in position. T T

' Sheet metal, as usual is employed in the construction of the twomembers of the gage, and the prong 4 is integral with the head indicatedas a whole by the numeral 5, which has a vertical wall or wallperpendicular thereto indicated at 6 forming the gage for the sheets 3.The gage has lateral tudinal bracing of the gageas well as the besttransverse bracing of the gage, because of the fact that thelongitudinal axes of the teeth, in pairs, are arranged at right angles.Thus between the prong at and the two pairs of teeth'the gage is heldfirmly in position, and the'separation of the teeth 8 and 8 from thepoint of engagement of the prong with the .tympan sheet permits theutilization of more material therebetween so that the paper sheet'isless likely to tear or break. In this manner the chances of the gagebecoming loosened or turned are eliminated and a more firm hold on thetympan sheet is secured.

The guide shanks 9 9 extend backwardly from the head an d are fashionedwith pres sure finger 10, 10, asusual, which are resilient' and adaptedto be pressed firmly against the tympansheet bracethe gage. In Figs.

jects through, to add firmness and stability" to the bracing of thegage.

The adjustable slide tongue 11 projects from its body portion 12, whichis formed with the projections or presser feet or tension feet 13, 113,frictionally engagingand slidable on the shanks 9 9, and at 14, 14lateral guide flanges are provided on the body of the tongue to slidealong the edges of the I shanks when the tongue is being adjusted,

and to retain the tongue in proper position.

As stated in the objects, it is one of the features' of the presentinvention to render more stable the adjustable sliding tongue, so thatthe latter will remain in fixed position, after adjustment, withoutlikelihood of disarrangement, and this is accomplished by, providingindentations 13' in the feet 13', 13,

which materally assist in enhancing the resiliency of said feet andenable the same to exercise a greater degree of pressure upon the guideshanks 9, whereby when thebody portion 12 is adjusted longitudinallvofsaid shanks, the same will be securely held in' a' frictional manner inconnection therewith, and hence loss of adjustment on the part'of saidbody-portionwill be rendered extremely unlikely.

The tongue projects through the slot 15 in the end wall of the age headand at this point is fashioned with sharp corrugations formingrack teeth16 that are engaged by the rib 17 stamped through the material of thegage head 5and projecting from/the under-side of the head. The'wall 15of the slot 15 also engages these rack teeth, the wall and rib beingadjusted with relation to the teeth so ,thattheyvwill engagecomplementary teeth, and the'r'esiliency of the material of which thetongue is ,made tends to hold the tongue in contact with the wall edge15 and the rib, so that thetongue may be adjusted to proper position andwill there be held firmly fixed,'as desired. Ashould'er in the tympansheet. 'Thefrear endsof the shanks are notched at 20, 20 to accommodatethe flanges 14 of the tongue bod'y when the parts are being assembled,and

after the tongue is passed through the slot tongue having its forwardfree end projecting through the slot of the head and its rear endmovable in the space between said "shanks, said rear end of said tonguehaving a laterally enlarged body overlying the shanks and provided withextension feet projecting longitudinally along the upper surfaces ofsaid shanks.

2. A-feed-gage comprising a slotted head having a rearwardly projectingpron and rearwardly projecting spaced sha s, a tongue having its forwardfree end projecting through the slot of the head and its rear endmovable in the space between said shanks, said rear end of said tonguehaving a laterally enlargedfbody overlying the shanks and provided withextension" feet projecting longitudinally alongthe upper surfaces ofsaid. shanks, said tongue also having "a vertical shouldered portionforwardly of its said enlarged body to engage the said head at theforward end of the shanks." f

3. A feed gage of the character described, comprisin a transverselyslotted gage head,

having a s oulder, a transverse rib, and provided with a lengthwiseprong, longitudinally extending shanks, a len hwise adjustable tongue,having side anges-proder formed on the tongue engageable with the headfor the purpose described.

5. A feed gage comprising a slotted head having a rearwardly projectingpron and rearwardly projecting spaced sha s, I a tongue having itsforward free'end pro'ecting through the slot of the head and rear endmovable in the space between said shanks,- said rear end ofsaid tonguehaving a laterally enlarged body overlying the shanks, and extensionfeetprojectin'g longitudinally fromsaid body; and disposed tofrictionally engage .the upper surfaces of saidshanks, said feet beingprovided with "indentations which operate to'enhan'ce 'the' its having arear portionslidably engaging the i wardly against the tongue engagingportion V frictional grip between said feet and the upper surfaces ofsaid shanks.

6. A feed gage comprising a slotted head, having a rearwardly projectingpron and rearwardly projecting spaced sha s, a tongue having its forwardfree end projecting through the slot of the head, the rear end of saidtongue being provided with a body portion disposed to slidably engagesaid shanks and to be adjustable longitudinally of the latter and curvedresilient feet disposed to engage the uppersurface of said shanks tomaintain said body and the tongue thereof in their positions ofadjustment With respect to said shanks.
